DDR could only help a FEW people...
and by a few i mean those few who are so hopeless in finding a beat that they need a flashy videogame to teach them.
All one does in DDR is "UP, DOWN, LEFT, LEFT, UP-RIGHT, DOWN-LEFT, RIGHT, RIGHT, LEFT-RIGHT, UP-RIGHT-LEFT-DOWN-RIGHT-LEFT-UP-DOWN, RIGHT-LEFT, RIGHT-LEFT, FREEEEEEZE!"
And that's it! That's all they do! (Haha, guess who never got higher than a 'C' score in DDR... I guess I AM kind of bitter lol) If you could go on Kazaa and download the music, that would be even better than wasting money on the damn game.
Or, give your fingers an exercise and play it online for free at
http://www.flashflashrevolution.com . Learn a beat there.
But if you could get a nice lookin top with DDR, then I congratulate you.
